If we subtract 0 from 94, we get 94.
Bring next digit (0) of the dividend behind the 94 and repeat the process: 940 / 639

On to step 3:
940 divided by 639 is 1 with a remainder of 301.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 639 from 940, we get 301.
Fetch the next digit (9) from the dividend, attach it to 301 and continue: 3019 / 639

Let's proceed to step 4:
If we divide 3019 by 639, we get 4 and a remainder of 463.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 463 after subtracting 2556 from 3019.
Bring next digit (8) of the dividend behind the 463 and repeat the process: 4638 / 639

Step 5:
639 goes into 4638 7 times with a remainder of 165.
Use 7 as the next digit of our solution. 
Result so far: 147.0
Deduct 4473 from 4638 and we're left with 165.
Grab the next digit (4) from the dividend, add it to 165, then carry on: 1654 / 639

On to step 6:
1654 divided by 639 is 2 with a remainder of 376.
Use 2 as the next digit of our solution. 
Result so far: 1472.0
The remainder is 376 after subtracting 1278 from 1654.
Bring next digit (5) of the dividend behind the 376 and repeat the process: 3765 / 639

On to step 7:
The number 639 fits into 3765 5 times, leaving a remainder of 570.
The next digit of our result is 5. 
Result so far: 14725.0
If we take 3195 away from 3765, we end up with 570.
Append the next digit (1) from the dividend to 570 and continue with: 5701 / 639

Going ahead to step 8:
639 goes into 5701 8 times with a remainder of 589.
Use 8 as the next digit of our solution. 
Result so far: 147258.0
The remainder is 589 after subtracting 5112 from 5701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Moving on to step 9:
5890 divided by 639 is 9 with a remainder of 139.
Record the quotient 9 as the next digit in the result. 
Result so far: 147258.9
Subtract 5751 from 5890 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 10:
1390 divided by 639 is 2 with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 147258.92
The remainder is 112 after subtracting 1278 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
When dividing 1120 by 639, we get 1 with a remainder of 481.
The next digit of our result is 1. 
Result so far: 147258.921
Subtract 639 from 1120 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Step 12:
639 goes into 4810 7 times with a remainder of 337.
Use 7 as the next digit of our solution. 
Result so far: 147258.9217
Subtract 4473 from 4810 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 13:
639 can be fit into 3370 5 times, resulting in a remainder of 175.
The next digit of our result is 5. 
Result so far: 147258.92175
Deduct 3195 from 3370 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 14:
The number 639 fits into 1750 2 times, leaving a remainder of 472.
Write down 2 as next digit of the result. 
Result so far: 147258.921752
If we subtract 1278 from 1750, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 15:
The number 639 fits into 4720 7 times, leaving a remainder of 247.
Record the quotient 7 as the next digit in the result. 
Result so far: 147258.9217527
The remainder is 247 after subtracting 4473 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 16:
639 can be fit into 2470 3 times, resulting in a remainder of 553.
Write down 3 as next digit of the result. 
Result so far: 147258.92175273
If we take 1917 away from 2470, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

The final outcome is 147258.92175273, with a leftover of 5.53e-07.
